IMPROVEMENT IN ELECTRIC APPARATUS FOR GAS-BURNERS.

Specification forming part of Letters Patent NO. 209,016, dated October15, 1878; application filed January 14, 1878.

To all whom it may concern:

Be it known that I, A. LIVINGSTON BOG-ART, of Jamaica, in the county ofQueens and State of New York, have invented an Improved Apparatus forLighting and Turning On or Off Gas-Jets by Electricity; and I herebydeclare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawing, making a partof this specification.

This invention relates to that class of gaslighting apparatus in whichany number of jets may be turned on and at the same time ignited by onemovement of a switch, pressbutton, relay, or other circuit-closer, and,if desired, any one burner may be turned on and ignited singly by alever upon that individual burner, the said burner, after such ignition,being automatically cut out of the circuit.

It consists in certain improved constructions and novel combinations ofparts, hereinafter particularly described, by means of which the gas maybe. turned on and ignited or turned off simultaneously in any number ofburners at a distance; or, if desired, any one of such burners may belighted independently of the rest.

In the accompanying drawing, Figure 1 represents a front elevation ofimproved burner; Fig. 2, a side elevation of the same, showing one modeof connection with the battery and a circuit-closer Fig. 3, a rearelevation; and Fig. 4, a rear elevation, the gas being turned on.

In Figs. 1, 2, and 3 the gas is turned off, and in Fig. 4. is turned on.

Similar letters of reference indicate the same parts in each of thefigures.

A is an ordinary stop-cock, having a metallic pillar, B, provided with alava gas tip. Secured to this lava tip, and thereby insulated from thepillar B, is a metallic ring, D, provided with a metallic electrode, F.

G is an arm, rigidly secured upon the stem of the cock, and movingtherewith, its'movement being limited to an angle of about ninetydegrees and upon the upper end of this arm G is an elasticcontact-point, H. Aflixed to the stem of the cock and a stationary post,I, is a spiral ribbon-spring, K, coiled upon the said stem in suchposition that, the gas being turned oh, the said spring on being broughtinto play will turn it on again, and at the same time carry the arm Gforward, so that the two points make and break contact and produce aspark.

J is a lever, rigidly secured to the stem of the cock, for turning on oroil the gas by han d.-

Upon the lower part of the burner, which is composed of cast ormalleable iron, is wound a helix of insulated wire, L. An armature, M,is pivoted at a, and provided with a spring, 0, which keeps it a shortdistance from P, and is provided also with a lever, It, and a catch, 8,so that when the gas is fully turned off the prolongation T of the arm Gwill engage with the catch 8, and prevent the spring K from turning onthe gas untilthe armature M is moved to 1?, either by the attraction ofthe magnet L or pressure upon the lever B, and the said spring isthereby released.

Q is a block of hard rubber or other suitable insulating materialsecured to the base of the burner; and attached to it by the screw '13is a metallic spring wire, (I, provided with an insulating sleeve orcovering, e, at its farther end. 00 andyare two insulated pins,connected, respectively, with the screws w and y.

Then the gas is turned on, as in Fig. 4, the spring (I rests against thepin y,- but on turning off the gas the arm '1 encounters e, and pressesthe spring (1 against the pin as. One end of the wire forming the magnetL is connected internally with cast-iron core, and its other end isconnected to the screw 00.

S may represent a battery, one terminal, a, of which is connected to theground or the gas-pipe, and the other divided into two circnits, one ofwhich, a, first passing through a small resistance-coil, V, is thencecarried along and attached to the. screw in the ring D of each of theburners in circuit. The other circuit, an, is provided with acircuit-closer, WV. of any suitable description, and thence runs to thescrew or post I of the nearest burner, and is attached thereto.

In the normal condition of the apparatus the circuit-closer WV is openand the burners turned ofi, as shown in Figs. 1, 2, and 3.

The operation of the apparatus is as follows: If the circuit at W beclosed, the current will travel along the wire m to the screw i throughthe spring-wire d, and, as it is prevented from reaching the ground bythe insulation at 0, will be conducted by the pin 00 into the magnet Land its connect-ions to the gas-pipe, thus causing the magnet L toattract the armature M and withdrawing the catch 8 from the arm T; andthe said arm being thus released, the spring K will rotate the stem ofthe cock A. As soon as the arm T is thus set in motion, the spring-wire(l is released and moves away from the pin 0:, thus entirely breakingthe circuit in the magnet L. B y the rotation of the stem through theaction of the spring K, as above described, the elastic contact-point onthe arm G next makes contact with the fixed electrode F, and the currentthen passes from the battery S through the coil V, the wire a, the ringD, and fixed electrode F, and the elastic point and arm G to thegas-fixture and ground; and by the continued forward movem ent of thearm G the connection at Fis broken and a spark produced, which ignitesthe issuin g gas. Just before the arm G has reached its point of rest,as seen in 4, the spring (Z is arrested in its movement by the pin ymaking contact therewith; and from the screw g, which is connected wit-hthe pin y, a connection, 12, is made to the next burner in circuit, inwhich latter the same operations are re peated, and so on through theseries of burners.

When the burners are all turned off any one of them may be lightedsingly by pressing down the lever It and thus releasing the arm T, thespring (1 thereby breaking contact with the pin w, and thus cutting suchburner out of circuit; but as the current can then pass from 1 through dand out at y, the other burners in circuit are still in condition to beoperated.

It is obvious that if the winds of the spring K were reversed theburners would then be in condition to be shut off by the circuit-closerXV, instead of being turned on, as above described, having beenpreviously turned on and lighted by means of the lever J.

This invention is more especially designed to be used in connection withburglar-alarms, and with city fire-alarm telegraphs. YVhen used inconnection with the former, connections are made to an electricburglar-alarm in such manner that upon the first tap of the bell whichindicates the opening of a door or window the burner-circuit will beclosed, thus turning on and igniting one or more burners in such partsof the building as have been prearranged to be lighted; and when used inconnection with the latter, any predetermined number of burners at afire-station will be turned on and ignited at the first stroke of thegong indicating the locality of the fire, thus avoiding delay in turningup lights and saving expense. It is also applicable for lighting signalson railroads, draw-bridges, 85c.

A. small battery only is required, as the power of the electricity isnot employed for rotating the plug of the cock, as in prey ious devicesof a similar character.

I do not claim as my invention the ring D, nor the elastic contact-pointH on the arm Gr; nor do I claim, broadly, the spring K for op cratingthe plu IVhat I claim as my invention isl. The spring K, in combinationwith the catch 8, the lever 1t, and the arms T and Gr, rigidly securedupon the stem of the cock, as and for the purpose set forth. 2. Thecombination of the magnet L, arm ature M, provided with the catch .9,arm T, spring K, arm G, carrying the elastic contactpoint, and the fixedelectrode I, as and for the purpose set forth.
